CONE OR FORMER FO R FELT-HARD ENING MACHINES.

SPECIFICATION forming part of Letters Patent No. 404,362, dated May 28,1889.

Application filed December 26, 1888. Serial No. 294,618. (No model.)

To all whom it may concern.-

Be it known that we, JOHN PENDERGAsT, of Boston, in the county ofSuffolk, State of Mass sachusetts, and DANIEL PENDERG-AST, of Merrimae,in the county of Essex, State of Massachusetts, have invented acertainnew and useful Improvement in Cones or Formers for Felt- HardeningMachines, of which the following is a description sufficiently full,clear, and exact IO to enable any person skilled in the art or scienceto which said invention appertains to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which Figure 1 is a top plan view of our improvedformer; Figs. 2 and 3, sectional views illustrating details ofconstruction, and Figs. 4 and 5 like views showing a modification of theimprovement.

Like letters of reference indicate corrcsponding parts in the differentfigures of the drawings.

Our invention relates to cones or formers employed on machines forhardening felt goods, as boots, shoes, hats, &c.; and it consists incertain novel features, as hereinafter fully set forth and claimed, theobject being to produce a more effective device of this character thanis now in ordinary use.

0 The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation.

The former A consists of a flat body com- 3 5 posed entirely ofwire-cloth f. It may be tapered or curved at one end, as shown in Fig.1, or constructed in other shapes suitable for the character of thegoods being manufactured. The edge of the cloth is bound at z to preventthe ends of the wires from catching in the felt and rendering itdifficult to remove the former from the bat. The binding .2 may consistof a strip of metal secured to the ends of the body and filling wires ofthe cloth, or said ends may be soldered together, the latter methodbeing preferable, as the binding thus constructed is practically ofequal thickness with the body of the former, rendering its operation onthe bat more effective. We prefer to employ galvanized wire-cloth, asthe cone thus formed is much stiffer and more readily handled, the Wiresbeing thusseeured firmly together, as shown in Figs. 2 and 3.

To obtain additional rigidity, we sometimes use two sheets ofwire-cloth, placed one above '5 5 the other, as shown in Figs. 4 and 5,and secured together by a metallic binding-strip,'m.

It will readily be seen that when the bat is folded or formc d onto ourimproved former and manipulated upon the steam-table in the usual mannerthe felt comprising the bat will be forced into the opening between thewires of the cloth, or the ribs or corrugations of the cloth willpenetrate into the felt and prevent the bat from slipping on the former.

The action of the steam upon the bat is also more thorough than isordinarily the case, as the former offers slight resistance to itspassage.

The action of the heat and moisture upon the Wooden formers in ordinaryuse frequently causes them to become misshapen and practicallyuseless-an objection which is obviated by our improvement.

Having thus explained our invention, what we claim is 1. A former forshaping a completed wool bat during the hardening process, consisting ofa flat body composed entirely of wirecloth, substantially as set forth.8o

2. A former for shaping a completed wool bat during the hardeningprocess, consisting of a flat body composed of two sheets of wireclothand a metallic binding-strip uniting, said sheets at their edges,substantially as set 8 5 forth.
